A. Why your crawler is always blocked? IP address is exposed!
Recently, a friend doing e-commerce complained to me that the crawler script he wrote was blocked after three days of running. I took a look at the log records and found that the problem - this buddy with his own broadband IP rigid platform anti-climbing system, deserved to be blocked ah! Like going to the supermarket to try to eat every time to wear the same fluorescent green jacket, the security guards do not stare at you to stare at who?
Here's one.Key knowledge points: The website wind control system will identify abnormal traffic by IP address. If you always use the same IP for high-frequency access, the traffic will be limited if it is light, or permanently banned if it is heavy. The solution is simple - make the program act like a real user andEach visit carries a different "Web ID."(aka IP address).
II. Teaching you to build a "virtual ID card"
Prepare the raw materials first (the library to be installed):
pip install faker requests
Upper hardcore code (with detailed comments):
from faker import Faker
import random
def generate random IP()::
Use Chinese variable names to be more grounded
Virtual ID Generator = Faker()
Randomly pick a common IP segment in China
Provincial IP pool = {
'zhejiang': ['36.26', '122.225'],
'Beijing': ['123.113', '210.75']
}
Random province = random.choice(list(province IP pool.keys()))
first three segments = random.choice(province IP pool[random province])
end = str(random.randint(1,254)) avoid 0 and 255
return f"{first three segments}. {random.randint(1,254)}. {end paragraph}"
Third, how to use the generated IP to be safe?
Attention! Stuffing fake IPs directly into the requests won't work, you have to use a proxy server to do the relay. It is recommended to useQuality proxy services from ipipgo, they have a package that is especially good for newbies:
| Package Type | Number of IPs | Applicable Scenarios |
|---|---|---|
| Beginner's Taster Pack | 500 per day | Small Data Acquisition |
| Enterprise Exclusive Edition | unlimited | Long-term crawler business |
Example of live code (remember to replace it with your own ipipgo account):
import requests
proxy settings = {
'http': 'http://用户名:密码@gateway.ipipgo.com:9020',
'https': 'http://用户名:密码@gateway.ipipgo.com:9020'
}
response = requests.get('destination url', proxies=proxy settings, timeout=10)
Fourth, the old driver only know the anti-blocking skills
1. IP switching tempoDon't be too regular. Randomize your stops like a real person.
2. In conjunction with the User-Agent randomizer (recommended fake_useragent library)
3. The use of ipipgo is recommended for important data collection.Long-lasting static IPStability is 3 times higher than dynamic IP
4. Don't fight hard when encountering CAPTCHA, go to a coding platform if you need to.
V. Frequently Asked Questions QA
Q: Can I use my own generated IP?
A: The generated fake IP can only be used to forge request headers, the actual network request must go through a regular proxy server like ipipgo.
Q: Which one to choose, dynamic IP or static IP?
A: Short-term collection with dynamic IP (cheap), long-term business with static IP (stable). ipipgo background can switch types at any time.
Q: What should I do if my proxy IP is slow?
A:在ipipgo控制台筛选低于50ms的节点,建议优先选本省IP段。
Lastly, I would like to say something from the bottom of my heart: data collection is like playing a cat and mouse game, using the right tools can get twice the result with half the effort. I recently used ipipgo's enterprise version, their technicians can also help customize the anti-blocking strategy, which is one of the few reliable players in the proxy service.
